A few tests that require running CPUID do so with a private implementation of a wrapper for CPUID. This duplication of the CPUID wrapper should be avoided but having one is also unnecessary because of the existence of a macro that can be used instead.
This series replaces private CPUID wrappers with calls to the __cpuid_count() macro from cpuid.h as made available by gcc and clang/llvm.
